Embodiment
Embodiment 1, the present embodiment a kind ofly has the whether consistent device of all pilot lamp brightness of the electronic product of one group of pilot lamp for testing gateway etc., principle adopts photosensitive device, as photoresistance, such photoresistance is penetrated lower resistance in the illumination of pilot lamp and will be diminished, then the size by detecting photoresistance represents the brightness of pilot lamp, when photoresistance resistance is less, illustrate that pilot lamp brightness is stronger, otherwise, when photoresistance resistance is larger, what reflect is that pilot lamp brightness is more weak, and schematic diagram as shown in Figure 1.If adopt the photoresistance that one group of characteristic is consistent, the light receiving a pilot lamp is respectively received as adopted the photoresistance of same batch, if the resistance of these photoresistance is identical, then think that these pilot lamp brightness are consistent, certainly, prerequisite is these pilot lamp is all the same with the relative position of photoresistance, simultaneously mutually isolated again, can not mutually disturb.
The specific practice of the present embodiment is as follows:
First, obtain the amount that reflection is relevant to each pilot lamp brightness, here adopt the distance apart from tested pilot lamp equal, and the identical photosensitive device (photoresistance) of tested pilot lamp direction of illumination obtain the reflection amount relevant to each pilot lamp brightness; In this step, adopt the brightness of photoresistance reflection pilot lamp, key refers to that the position relationship between pilot lamp with photoresistance wants consistent here.Resistance value when irradiating under tested pilot lamp the same terms by measuring photoresistance is as the correlation of tested instruction brightness.Reflected resistance value can be carried out by the voltage measuring photoresistance two ends, finally magnitude of voltage digitizing can be compared.
Next obtains standard value; This step Plays value, standard value has a lot, can be median or the average of one group of measured pilot lamp correlative, also can be empirical value when usually detecting.
The last amount relevant to each pilot lamp brightness step 1 obtained successively compares with standard value, if there is difference to be greater than the thresholding of setting, then judgement pilot lamp and other pilot lamp brightness inconsistent and indicate this tested instruction and other pilot lamp brightness inconsistent.Threshold value is empirical value.
